ELI5: Explain Like I'm 5

Damage tolerance

Okay kiddo, imagine you have a toy car. Now, you love playing with it and sometimes you accidentally hit it against walls or drop it on the floor. But every time you do that, the toy car doesn't break or get damaged too much. That's because it has something called "damage tolerance."

Now, imagine a big airplane. It's similar to your toy car in that it can get damaged if it hits something or there's a problem with its parts. But airplanes are much bigger and much more important than your toy car! So it's really important that they have a super high level of damage tolerance.

The people who build airplanes want them to be able to handle some damage without breaking or crashing. So they design and build planes in a way that means they can take a lot of wear and tear, and still keep on flying safely. They use very strong materials, like metals and composites, to make the planes as sturdy as possible.

To make sure airplanes are really good at damage tolerance, they also test them a lot. They'll purposely damage parts of the airplane, like the wings or the engine, and see how well it holds up. They'll also do regular checks on the plane to make sure there aren't any hidden problems that could cause damage.

So you see, damage tolerance is all about making things that can withstand damage without breaking. It's especially important in things like airplanes, where people's lives are at risk if something goes wrong. But even your toy car benefits from having some damage tolerance, because it means you can keep playing with it even if you accidentally bump it around!
